Compared to a regular roof panel roll forming machine, a standing seam roll forming machine has smaller sizes in body but more sophisticated rolling tools .

First of all, machine designers innovated the Standing seam roll forming machine for producing the metal roof panels out of pre-painted steel, zinc-coating or galvanized steel, zincalume/galvalum steel, and occasionally aluminum as well.

Usually, the material thickness varies from 0.4-0.8mm, but some other concealed fix standing seam roofing, like BEMO roof sheets are thick from 0.8-1.2mm. The material width for a standing seam panel covers from 400mm-1000mm, while a regular roof panel roll forming machine handle with the material of widths at least 914mm and max. 49″ widths.

Firstly, the standing seam roof panels have a concealed fxing or seaming method by turning up the edges of two adjacent panels, and then folding or interlocking them.  In this way, the seaming or fixing parts are invisible,  and therefore sometimes we called the panels concealed fixing panels! The machine got its name as concealed fixing standing seam roll forming machine accordingly!

In Chinese markets, customers can usually find  470 and 820 type concealed fixing standing seam roll forming machine, while in North American market, particularly in Mexican market, people like to give them the name LR18/KR 18 or LR24/KR24 standing seam roll forming machine for roofing sheets.
